Injection Mold Layout Sheets are very important
Regardless of mold type, the goal of a maintenance shop always is the same: get a mold production-ready after it has been removed from service. […]
Introduction to Heater Construction
In order to understand the causes and related problems associated with heater failure we should first understand the construction of a heater. […]
Introduction to Temperature Control Types of heater
Temperature control has a great deal to do with the life of your heater. There are many different types of temperature control on the market today. It will be impossible to cover all of them, so this article will cover the benefits, as they would affect heater life. […]
Introduction to Heater Removal
Heater removal can be very difficult, if the heater has arc welded itself to the inside of the heater hole. You will continue to experience heater failure if the heater is not removed with care. When a heater is removed by drilling with a size-for-size drill, the drill will cause scallops in the heater hole, [...]
Limitations of rotational molding and Material requirements
Rotationally molded parts have to follow some restrictions that are different from other plastic processes. As it is a low pressure process, sometimes designers face hard to reach areas in the mold. Good quality powder may help overcome some situations, but usually the designers have to keep in mind that it is not possible to [...]
Introduction to Advantages of rotational molding
Rotational molding offers design advantages over other molding processes. With proper design, parts assembled from several pieces can be molded as one part, eliminating high fabrication costs. […]
Design considerations of rotational molding
Product designThere are many considerations for a designer when designing a part. Which factors are most important to a client? […]
Introduction to Production process of rotational molding
The rotational molding process is a high-temperature, low-pressure plastic-forming process that uses heat and biaxial rotation (i.e., rotation on two axes) to produce hollow, one-piece parts. […]
Introduction to Rotational molding machines
Rock and roll machineThis is a specialized single arm machine. It rotates or rolls the mold 360 degrees in one direction and at the same time tips and rocks the mold 45 degrees above or below horizontal in the other direction. […]
